Vehicle air duct structure

Abstract: A vehicle air duct structure comprises a substantially tubular air duct body and an inner guide wall. The air duct body extends from an inlet end to an outlet end with a curved portion disposed therebetween to convey an air flow from the inlet end to the outlet end. The inner guide wall is integrally formed with the air duct body as a one-piece, unitary member. The inner guide wall is configured and arranged to separate the air flow into a plurality of branch flows in the curved portion. The air duct body further includes a generally linear portion disposed adjacent to an upstream end section of the curved portion. The inner guide wall continuously extends along a direction of the air flow in the curved portion and at least a part of the generally linear portion of the air duct body.
